I have a question. The s2000 with compresion ratios we have not seen since leaded gas, except with racing fuels. Turbo/supercharging increases volumetric efficiency and therefore the compression ratio. Normally aspirated engines do well if they get to 85% volumetric efficiency. Obviously, preignition from too high a compresion ratio will occur with wide-open-throttle at full loads.

Here is the question. I have been thinking of using an electric engine (which could be turned on an off anyway) to supply an air induction into the intake manifold. This electric motor will produce all of its boost even at low RPMs and there would be no lag. My idea is to supply enough air to boost volumetric efficiency at low rpms, let's say between 2000--6000, beyond that, the engine vaccuum would exceed the output from the electric motor returning the curves to normal aspiration. I have not calculated the amount of air required but that is a simple matter. I can't draw the diagram right now since I am at work and the boss is watching (Oh I forget, I am the boss). It could be added to the intake pipe below the normal air filter. We use air induction which actually works at high speeds only. This would be a way to increase the power at the low end and not worry about preignition.

By the way, to clarify something, all forced air inductions are superchargers. Turbo, belt driven or even this. The termis being missused. We have turbosupercharges, belt driven ones, etc.

 

[QUOTE=4cpu,Aug 31 2006, 09:28 AM] Here is the question.

 

I have seen these in person. I think most would agree with me when I say its not worth the effort. Horsepower gains will be minimal at best.

 

It's the several hundred pounds of batteries that slow you down.

 

If you have not already seen them, search for my previous posts in FI about electric supercharger. I have done some research, but so far I have not done anything else about it. Very few people have any experience with this sort of thing. Leader in the field seems to be Thomas Knight at Boosthead.com.

 

As already posted, I'm afraid the OP is in for a sad surprise. The "ELECTRIC SUPERCHARGER" is already marketted and has been available for years. This has been discussed in this forum on many occasions in the past and has largely been dismissed as very poor return for the amount of energy draw these things suck up. Too little, too late.
I tried to make a suggestion that this is not a problem if a long extension cord were to be used, but people just laughed at me at the time and dismissed it as a truly stupid and dumbass idea.

 

Do you mean to have a 1/2 mile long extension cord or something that would enable you to leave the batteries and such equipment outside the car???

 

Well, something like that. I had several options.

1. Get 28 X 100' extension cords all hooked together and stay within about a 1/2 mile from home. I'd have to do "U-ies" and come back the way I came so the cord wouldn't get all tangled up.
2. Get 14 X 100' extension cords all hooked together and find a 1/4 mile race track that will let me "plug in" at the starting line.
3. Get another car (preferable a Vette Z06) and put on a trailer hitch. Have a heavy duty generator on the trailer that the Z06 would pull. That way, I only need 1 X 100' extension cord and follow the Vette. The Z06 is critical. Anything less and I'd probably ram the thing. I mean, who knows how many HUNDREDS of extra HP I'd be pushing with an ELECTRIC SUPERCHARGER. Trouble with this scenario is that the Z06 may have to be governed or it might get too far ahead of me and disconnect the cord.

I had other ideas, too. Did I mention how my leaf blower idea was received?
It's OK, I'll show them. I've got TWO of them duct taped in TANDOM??


Oh, and there was this time when I tried the "ram air" supercharger. I don't know why people made fun of me.


I'm in the process of coming up with my "air raid siren" supercharger. It involves having a passenger work the hand crank really, really fast.

DISCLAIMER:
Everything that followed this post:
Was NOT intended to make fun of the OP. It was purely intended to set myself up to have others get a laugh at my expense. Afterall, that's what the Forum Jackass is supposed to do, right?

 

hahahaha

 

i saw a pick up get like 40 hp from a leaf blower on a dyno, like 100 when they were shooting the nos bottle into the blowers intake
